Re: Fwd: sed porting trouble

This is an OS on which gnulib was never tested so far. Therefore I have to
start with a few basic questions:

  - What is the official name of the OS? NonStop? NonStop OS? NonStop UX?
    Also the version number (for reference in gnulib documentation)?

  - What is the result of config.guess?
      $ sh build-aux/config.guess

  - What are the predefined C compiler macros? __TANDEM, what else?
    __hpux also?

Then, three questions about the ACL support. First, where is a reference of the
API? I need this info for updating
  
<http://git.savannah.gnu.org/gitweb/?p=gnulib.git;a=blob;f=doc/acl-resources.txt>

  - Which include files declares functions related to ACLs?

  - Which symbols are defined? Something like
      $ nm /usr/lib/libc.so | grep acl
    should provide the list.

Just a test case: When you try to compile this file with "cc -c foo.c"
======================== foo.c ========================
extern int acl (char *);
int foo (const char *s) { return acl (s); }
=======================================================
what is the result?

gnulib contains a couple of unit tests for this code. sed-4.2.1 doesn't.
Therefore I'd like to ask you to repeat your effort with this tarball:
  http://www.haible.de/bruno/gnu/acltestdir.tar.gz

With your changes, does only the compilation pass, or does "make check"
also pass?

Try to only preprocess the file:
  $ cc -DHAVE_CONFIG_H -I. -I.. -I../lib -I.. -I../lib -I/usr/local/include -g 
-E btowc.c > i.c
and look at i.c. Here it should be easier to spot which tokens before
'struct random_data' are confusing the compiler.
